Porous structure and method for manufacturing same

Abstract

A porous structure according to the present invention has a polymerase chain reaction (PCT) primer inside pores thereof, and hence, even an inner portion thereof can be used unlike general structures of which only surfaces are used for amplification and detection, thereby maximizing reactivity. In addition, the differentiating of the kinds of primers contained in respective structures leads to detection of several kinds of target nucleic acids at the same and real-time analysis thereof at the same time, and thus is useful for multiplex real-time PCR.

The invention claimed is: 
     
       1. A porous structure comprising a cured polymer having pores,
 the porous structure comprising primers in one or more directions between a forward primer and a reverse primer of a target nucleic acid as a primer of polymerase chain reaction (PCR) fixed to the interior of the pores, 
 wherein a porosity of the porous structure is from 60 vol % to 80 vol % with respect to a total volume of the porous structure. 
 
     
     
       2. The porous structure according to  claim 1 , wherein a primer only in one direction between a forward primer and a reverse primer of a target nucleic acid is fixed to the porous structure as a primer of polymerase chain reaction (PCR). 
     
     
       3. The porous structure according to  claim 1 , wherein the porous structure is from 10 μm to 500 μm in size. 
     
     
       4. The porous structure according to  claim 1 , wherein a primer fixed to the interior of a pore of the porous structure includes an acryl group at a terminal, wherein the acryl group is chemically fixed to the porous structure. 
     
     
       5. The porous structure according to  claim 1 , wherein one or more primers among the primers fixed to the interior of a pore of the porous structure are linked to the porous structure via a linker. 
     
     
       6. The porous structure according to  claim 5 , wherein a length of the linker is from 5 nm to 100 nm. 
     
     
       7. The porous structure according to  claim 1 , further comprising an encoder to provide information corresponding to a fixed primer.
